JOHN F. HEMENWAY, OF NEW YORK, NTY.

AUTOMATIC PRESSURE-RELEASE FOR CLOTHES-WRINGERS.

Specification of Letters Patent. Patented Mar, 20, 1917.

Application filed September 9, 1916. Serial No. 119,178.

To all whom it may concern:

Be it known that I, JOHN F. HEMENWAY, a citizen of the United States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvementsflin Automatic Pressure-Releases for Clothes-'Wringers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements upon my automatic release filed even date herewith, the object being to provide novel means for adjusting the position of the release actuating member in order to enable the releasing device to be set so that the same will be actuated by different thicknesses of material through the wringer rolls.

Another object of my invention is to provide a releasing device which is composed of very few parts so arranged that they can be readily placed in position upon an ordinary construction of clothes wringer so that the pressure on the pressure rolls will be instantaneously released when a foreign object is drawn between the same.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings,

Figure 1 is a side elevation partly in section showing the application of my improved construction of releasing device to a clothes wringer;

Fig. 2 is an end elevation partly broken away to show the manner of mounting the actuated member on the upper pressure roll shaft;

Fig. 3 is a top plan view of a Wringer showing the releasing device applied thereto; and

Fig. 4 is a detail perspective view of one of the latch actuated members detached.

Like numerals of reference refer to like parts in the several figures of the drawing. In carrying out my invention I employ a wringer of the ordinary construction composed of a frame 1 having slotted side bars 2 in which are mounted bearings carrying pressure roll shafts 3 and 4 having meshing gears as clearly shown inclosed by a gear casing 5; The shafts 3 and 4 are provided with pressure rolls 6 and 7, and the upper bearing of the shaft 4 carries coil pressure passing springs 8 upon which are mounted bearing plates 9 having depending lugs as clearly shown, said bearing plates being carried by a pressure bar 10. The bearing plates 9 of the pressure bar 10 are engaged by pressure screws 11 carried by a top bar 12 movably mounted within the slotted portions of the side bars 2 and is provided with wear plates 13 at its ends adapted to be engaged by pivoted latches-14 for holding the movably mounted top bar in predetermined position within the frame so that the desired pressure canbe obtained on the pressure rolls through the medium of the pressure bars and pressure springs.

The pivoted latches 14 are provided with eyes 15 at their lower ends which register with spaced apertured ears 16 extending laterally from plates 17 secured to the upper end of the side bars 2 as clearly shown in Fig. 2, said apertured ears being spaced from the body of the plate 17 to form a guideway for an actuating stem 18 which is provided with a collar portion 19 having an elongated or oval-shaped opening through which the pressure roll shaft 4 extends, as clearly shown in Figs. 1 and 2. The stem 18 is preferably formed of a channel bar and extends under the cut-away portion formed on the under side of the pivoted latch 14, said latch extending between the flanges of the stem, as clearly shown in Fig. 2, the end of the cutaway portion being formed on an arc of a circle in order to provide a cam face 20 which is adapted to be engaged by the end of the stem so as to throw the pivoted latch outwardly out of the path of the movably mounted top bar so as to release the pressure means.

In order to provide means for setting the stem 18 of the collars 19 at the proper distance from the cam portion 20 of the latches,

I provide each of the collars with a set screw 21 which is adapted to engage the shaft and hold the end of the stem at the proper distance away from the cam portion leasing device can be set in such a mannerthat the pressure would be released by the passage of different thicknesses of material through the pressure rolls, as by ad usting the set screw so as to raise the stem upwardly, the release will be actuated by the passage of a medium thickness of material, and by adjusting the set screw so as to lower the stem of the collar, the releasing device will not be actuated unless an extremely thick wad of material or foreign object is drawn between the pressure rolls.

In the operation of the pressure release as herein shown and described, the upper pressure roll is free to move vertically a sufficient distance to allow ordinary'clothes to be wrung thereby, but when a foreign object is drawn between the pressure rolls the upper roll is lifted such a distance as to throw the stem of the collar into engagement with the am portion of the pivoted latches so as to force the latches outwardly from off of the wear plates of the top bar which instantaneously allows the top bar to move vertically and releases the pressure means.

I claim:

1, A clothes wringer, comprising a frame having pressurerolls and pressure means for said rolls, means for normally holding said pressure means in predetermined position, and adjustable means actuated by the vertical movement of one of said pressure rolls for releasing said means.
